And how do you know how much money these families bring in to make determinations about "wealth?" Does Google have more powers when its accessed from Utah?

In 2013, size should not equal strength. Chicago and Detroit are two strong borgatas where familial relationships run rampant throughout the organizations via marriage of their children...like Sarno's daughter marrying Jimmy Inendino's son or Albie Vena marrying a Spina. This is why rats are so rare in those cities. Creating a smaller power base and making a very select few (mostly those you are related to through marriage) is way more effective than having "150 made guys on the street" in 2013.
